as distinguished from anchors of the type for which holes are previously dug. A driven anchor ofthis kind is shown and described in Letters Patent of the United States No, 768,705 issued Augusti-BO, 1904 to W. WfSwan, and the present. invention has more particular reference to im "movements in the anchor :of that patent. it 1st anchor consists of a comparatively thin and narrow plate pointed at its entering end end provided at its rear end with a pnirof rearwardly curved points or spurs whichcause the driven anchor to turn perpendicularl to the line of pull when tension is upplie to the stay-rod attached to the front or upper side of the anchor-plate, so that the anchor presents its greatest area to the resistance of the soil.

One of the objects of 'our invention is the construction of an etlicientanchor 'of this character whichct'm be driven with com-' Further objects of the invention are to in-.

crease the strength of the anchor without materially increasing its weight; to provide the same with an increased bearing surface for the lower end of the driving rod, so as to efl'ectuully resist splittingor breakage of the anchor. and to improve the construction of the anchor in other respects, as herein- In accompanying drawings: Figure 1 is a sectional elevation showing the improved anchor applied to a fence post. Figs. 2 and 3 are perspective views of the anchor viewed,

from opposite sides. Figs. 4 and 5 are transverse sections thereof on the correspondingly numbered lines in Fig. 3. Fig. 6 is a side elevation of the driving bar on a reduced scale. T

Similarletters of reference indicate corresponding parts throughout the several views. "A. indicates the anchor, B the usual stay rod or wire pivotally attached to the upper seafront side of the anchor end provided at its upper end with the customary eye I), and C indicates the usual connection between said eye and the fence-post I) or other object to be stayed or braced.

The anchor consists of an oblong plate. preferably cast of malleable iron and point ed at its entering end, as shown at a, end providcdmt its opposite rear end with rearwardly curved points or spurs a, substan tially as in the anchor of the patent hereinbefore referred to. On its lower side the anchor plate is preferably provided with stifiening ribs e arranged in line with the spurs a, so as to reinforce the latter as well as the body of the anchor plate. On its upper side the anchor is provided abdnt midway of its ends with lugs F to which the lower end of the stay rod 1) is pivoted by a transverse pin f, so that the anchor plate is free to turn in line with or at an angle to the stay rod,in the usual manner.

f is an inclined brace extending downwardly from. the outer edges of the lugs F to the fe ce of the anchor-plate. This brace serves not only to stiilenjthe lugs, but :lso protects them from breakage by contact with a stone or similar hard obstruction, the inclihed face of the brece deflecting the anchor and relieving thelugs from undue strain in the event. of encountering such an obstruction in driving the anchor. The upper end of this brace forms a stop or shoulder f which is adapted to abut against the side of the stay-rod B when the anchor is sulostant-ially perpendicular to the rod. as shown in Fig. 1. By this simple provision, the anchor is prevented from tuning; beyond the position in which it presents its broad side to the soil and withdrawal of the anchor is obviated.

The anchor plate is provided at'or near its rear end with a longitudinal sOPlIQi G adapted to receive a suitable driving-bar H. the anchor being sunk to the desired depth by blows deliveredupouthe upper end of said bar, in a manner common to this class of anchors. The preferred socket shown in the drawings is cylindrical and the driving bar has a reduced lower end of corresponding form. This socket is preferably arthe driving bar and withstands a considerable impact without danger of breaking or forms a hole in the ground of larger diameter than the driving bar, thus providing the necessary clearance for easily withdrawmg the driving bar by hand. The arrange- .ment of the socket on the rear side of the anchor plate, that is. the same side as the curved points 11, as shown, affords the fur-,

';result is that the driving come bound on the anchor,

ther important advantage of counteracting the tendency of the points to cause the The tool does not bewhich isliable anchor to swerve or drive crooked.

' to occur when the anchor deviates from a fiance-post is connected with the'stay rod by object by after attaching the stay rod B to the anchor. the latter isdriven edgewise into the is turned at ri straight line in driving,'and the bar can therefore be easily detached from the anchor plate after driving it.

' The improvements'hereinbefore described, while materially increasing the, strength, convenience and efficiency of the anchor do not add to its cost, inasmuch as the. device can be'east in asingle piece. of n'iallcable iron or other suitable metal.

We claim as our invention:

-1 A groundanchor of thecharacter described, consistin of a plate provided with an attachment En a stay-member and a longitudinally disposed one side of the a driving-bar.

2. A ground anchor of the character described, consistin of a plate" provided with an attachment or a stay-member and a laterally-p ojecting socket for a driving-bar having a tapering front end, substantially as set forth.

A grou'nd anchor of the character de- I scribed, consisting of a plate provided at its rear end with one or more spurs curved E toward one side thereof, a socket for a' driv- 1 ing-bar arranged on the same side of the plate assaid spots. and an attachment. for a stay-member arranged on the o )posite side ofthe plate, substantially as set orth.

5. A ground anchor' of the character described, consisting of a late provided on its rear side 'with longitudinal stiffening ribs and a longitudinal socket for a drivin -bar arranged between said ribs, substantial y as set forth.

6. A ground anchor adapted to be driven into the ground by a detachable driving-bar and consisting of a plate having a pointed entering end. a pair of spaced lugs on one side ofthe plate for the attachment of a stav-member, and an inclined deflecting surface extending from the outer ends of said lugs: to the plate in the direction of its entering end.

T. A ground scribed, consisting of a plate provided on its upper side. at a distance from its ends with an attachment for a stay-member, and a stop adjacent to said attachment adapted to engage the stay-inember for limiting the turning movement of tlje stay-member.

8. In a ground anchor of the character described, the combination of an anchor-plate having a pointed entering end and provided on its front side bet ween its ends with a pair of lugs and a stop arranged at one side of the space between said lugs. a stay-member arranged between said lugs and adapted to abut against said stop, and a pivot-pin passing throngh said lugs and the stay-member.
